California's Giant Sequoia National Monument cleared its last legal challenge Monday as the Supreme Court declined to consider an appeal by Tulare County and logging groups.
The court's action, issued without comment, upheld President Clinton's creation of the 327,769-acre Giant Sequoia monument.
Tulare County officials contended the monument, about half the size of Yosemite National Park, is unnecessarily large.
The national monument is designed to protect some of the world's largest and oldest trees.
The sequoia groves themselves account for about 20,000 acres, or roughly 6%, of the total monument.
